Sep 12, 2017 · This tutorial will first go over the basic building blocks of graphs (nodes, edges, paths, etc) and solve the problem on a real graph (trail network of a state park) using the NetworkX library in Python. You'll focus on the core concepts and implementation.

ONNX Runtime provides various graph optimizations to improve performance. Graph optimizations are essentially graph-level transformations, ranging from small graph simplifications and node eliminations to more complex node fusions and layout optimizations.

In this chapter we will present models for three optimization problems with a combinatorial structure (graph partitioning problem, maximum stable set problem, graph coloring problem) and try to solve them with SCIP/Python.

# while scheduler.continual: # loss = optimizer.step(input=(edges, poses), weight=infos) # scheduler.step(loss) # name = os.path.join(args.save, args.dataname + '_' + str(scheduler.steps)) # title = 'PyPose PGO at the %d step(s) with loss %7f'%(scheduler.steps, loss.item()) # plot_and_save(graph.nodes.translation(), name+'.png', title, axlim ...

This is a python binding of graph optimization C++ framework g2o. g2o is an open-source C++ framework for optimizing graph-based nonlinear error functions. g2o has been designed to be easily extensible to a wide range of problems and a new problem typically can be specified in a few lines of code.

This is a python implementation of the pose graph optimization from scratch to understand the backend of Graph Slam. Moreover this can be used to implement a full graph slam solution in the future.
